Abstract: Under the mine, Shearer's hauling speed affected the shearer's efficiency and reliability. Taking MG32570*2/325-BWD shearer as research object, from shearer's reliability, by using Simulink, the intelligent speed regulation system was established, based on shearer key parts' reliability. The building & simulation of hauling motor load torque block and recommended optimum hauling speed generation block which was fitted by neural network was solved. The simulation results show that: this system can achieve the recommended speed, which is traced by hauling speed rapidly and accurately. When consistent coefficient and cutting depth are 2.85 and 0.58m, the hauling motor's maximum speed is 1142.06r/min, hauling speed can reach 4.85m/min. Because the hauling motor's tolerance is big enough, the shearer's productivity can increase by improving the weak parts' reliability, which can let the shearer get the optimal performance.

Key words: shearer, reliability, simulink, intelligent hauling
